w on they wanted plum pudding
every day.

On the upper Bavispe we again found numerous traces of a by-gone
race who had occupied these regions long before the Apaches had
made their unwelcome appearance. In fact, all along on our journey
across the sierra we were struck by the constant occurrence of rude
monuments of people now long vanished. They became less numerous in
the eastern part, where at last they were replaced by cave dwellings,
of which I will speak later.

More than ever since we entered the Sierra de Nacori, we noticed
everywhere low stone walls, similar to those we had seen in the
foot-hills, and evidently the remains of small cabins. The deeper we
penetrated into the mountains, the more common became these hut-walls,
which stood about three feet high, and were possibly once surmounted
by woodwork, or, perhaps, thatched roofs. All the houses were small,
generally only ten or twelve feet square, and they were found in
clusters scattered over the summit or down the slopes of a hill. On one
summit we found only two ground plans in close proximity to each other.

The stones composing the walls were laid with some dexterity. They
were angular, but never showed any trace of dressing, except, perhaps,
by fracture. The interstices between the main stones were filled
in with fragments to make the walls solid. Neither here nor in any
other stone walls that we saw were there any indications of any mud
or other plaster coating on the stones.

On top of a knoll in the mountains south of Nacori, at an elevation
of 4,800 feet, well preserved remains of this kind of dwelling were
seen. The house, consisting of but one room about ten feet square,
was built of large blocks of lava. The largest of these were eighteen
inches long, and about half as thick, and as wide. The walls measured
about three feet in height and one foot and a half in thickness, and
there was a sufficient amount of fallen stone debris near-by to admit
of the walls having been once four or five feet high. There were the
traces of a doorway in the northwest corner of the building. Numerous
fragments of coarse pottery were scattered around, some gray and some
red, but without any decoration, except a fine slip coating on the
red fragments.

In the Sierra de Nacori, on the summit of a steep knoll, and at an
elevation of about 6,500 feet, we found two huts of such laid-up
walls. The rough felsite blocks of which they were composed were
surprisingly la
